It appears to me that there is another problem with Internet Explorer (5 at
least, not sure about 4) when dealing with it's cache on one URL that I am
aware of so far.
If I go to http://www.national.com.au/banking/ via a bookmark/favorite that
I have with the same URL, it fails, with some of the images on the page
coming up, but two of the main frames failing "404 - not found". This is
confirmed by looking in my squid access log. If I then do a refresh on the
page, it comes up fine, but will fail if I subsequently go via the favorite
again. I have IE set to check for a newer version "Every visit to the page".
If however I go to the URL by typing it in directly into the location bar,
it comes up first time without a problem, and no refresh is required.
The problem doesn't occur with Netscape...
